Bison Gold Exploration Inc. Discovers New Tene West Zone at Central Manitoba

May 23, 2008 - Toronto, Ontario - Bison Gold Exploration Inc. (BGEI - CNQ) ("Bison Gold") is pleased to update shareholders on the company's recent exploration activities, which have been focused mainly on the Central Manitoba gold property located in the Bisset-Rice Lake belt in southeastern Manitoba. The Central Manitoba mine, which produced 160,000 ounces of gold during its 1927-37 production period, remains the second largest producer in the belt, next to the recently re-opened San Antonio mine at Bisset.

In late March, the company completed a 3242 meter drilling program on the Central Manitoba property. Previouys smaller drilling programs in 2006 and late 2007 had returned encouraging results from the Wentworth vein and Tene Deep Zone. The recent drill program comprised 16 holes which ranged individually from 62 meters to 452 meters in drill depth. Of these holes, six were stepouts extending the Wentworth vein along strike to the west, six were drilled between the Kitchener, Tene and Hope shafts along the Central Manitoba zone, three were drilled under the old mine workings, and one was a wildcat hole to the southeast along the prospective gabbro sill.

Results have been received to date on four of these 16 drill holes, including CM-08-1, -2, -3 and -6. Hole CM-08-1 was drilled directly under the old Hope mine workings, intersecting a strong shear zone, but only minor gold values including 1.0 g/t Au over a drill width of -.30m. Hole CM-08-2 was a wildcat hole drilled several hundred meters southeast of the Hope mine along the prospective gabbro sill, but no significant gold values were cut. Drill hole CM-08-3 was collared between the Tene and Hope shafts, and intersected several strong shear zones, with minor gold values up to 1.1 g/t Au over a drill width of 0.62m.

Drill hole CM-08-6 was drilled between the Wentworth vein, which has been the focus of most of the company's recent drilling, and the Tene mine. This drill hole, oriented at -50°/015° azimuth across the prospective zone, intersected a mineralized, quartz-veined shear zone that returned 6.0 gAult/2.98m [truth width 2.41m] at 70.70-73-68, including 10.4 gAult/1.55m [true width 1.26m] at 72.13-73-68m down hole. This new intersection, being called the Tene West vein, appears to be a strike extension of the Tene mine veins.

Results on the remaining 12 holes will be released as soon as they are received. Also during March, Bison Gold acquired by staking a 41 hectare claim lying immediately south of the Central Manitoba zone. This claim will cover any down-dip extensions that may arise from deeper drilling on the south-dipping Central Manitoba shear structure.

Commenting on the new Tene West discovery, consulting Geologist, William Hood stated: "We are intersecting good mineralization at shallow depths in the area of the Wentworth vein and west of the Tene mine. Historical records indicate that the original Tene No. 1 claim in this area was not owned by the mine in the 1927-1937 production period, but was only leased from others owners for 3 years, and, as a result, was under-explored with only minor production from a zone near the Tene shaft."

Bison Gold has commenced planning for its next drill program on the Central Manitoba property, which will include follow-up holes on the Central Manitoba zone, as well as drilling in the area of the nearby Ogama-Rockland mine which produced 45,000 ounces of gold during its 1948-1951 production period. Drilling is also being planned for the Apex gold property, located near Snow Lake in west-central Manitoba. In the Flin Flon area, Bison is evaluating its 10% back-in interest in Callinan Mining's War Baby claim, adjacent to Hudbay's Triple Seven mine.

"We are anticipating an exciting year for Bison Gold in 2008," said Lucas Ewart, CEO of Bison Gold, "especially in the developing Bissett-Rice Lake gold camp. We are well financed to explore our properties and to pursue other opportunities as they arise."

The Central Manitoba drilling program was completed under the supervision of William C. Hood, P.Geo., a Qualified Person under NI 43-101. Drill core was sawed and sent to SGS Mineral Services in Red Lake for analysis. SGS maintains a quality control program with standards, blanks and duplicates. Blank check samples were also inserted regularly. W.C. Hood has reviewed this news release.
